Relationship to the Drakensberg
editIn the article it is stated that the name bergwind "is named after the Drakensberg mountain range." However, I doubt that the name refers to the Drakensberg in particular, as the wind often blows down the western rather than eastern escarpment of southern Africa. Additionally, the flow pattern is sometimes also observed during late summer (it would appear from a statement in the article that it occurs during winter only) along the west coast[1] and is then often associated with the west coast trough (personal research, hopefully to be published) Cnrwil004 (talk) 11:37, 25 January 2013 (UTC)
- That's true - it isn't named specifically after the Drakensberg. The word "berg" simply means "mountain, not a particular mountain, any mountain will do. The rest of that sentence doesn't actually make sense - it looks like a fragment from a bad cut&paste move. I'm going to delete it now. Roger (Dodger67) (talk) 18:19, 25 September 2013 (UTC)

Foehn wind or Katabatic wind
editIn the articles on Santa Ana winds it is made clear that this phenomenon is not constitute Foehn winds, but are katabatic winds, as their hot, dry character is not due to flowing across mountain ranges and consequently losing moisture on the ascent, but rather as a result of mechanical compression of subsident air as it descends from the interior plateau. I would argue that at least some -- if not most -- berg wind events are caused by outflow of air from the interior plateau, where the Kalahari High dominates during winter. However, at times, berg winds may result from moist air ascending the Drakensberg,or other eastern mountain ranges, as it is advected onshore by a ridging South Indian or South Atlantic High, and then subsequently descending the western escarpment, devoid of moisture, causing occasional searing mid- and late-summer heat along the western coastal belt (in towns such as Paarl, Wellington, Vredendal, Clanwilliam and Vioolsdrif) — Preceding unsigned comment added by Cnrwil004 (talk • contribs) 12:24, 25 January 2013 (UTC)
Major expansion of the article
editThe article has been completely re-written, and expanded to include a full description of "coastal lows" which are an invariable accompaniment of berg winds. Cruithne9 (talk) 13:36, 4 June 2015 (UTC)
